Question

A particle with an electric charge of 2*10-3^C is a distance of 5 m from a particle with a charge of 8*10-5 C . What is the strength of the electrostatic force between the two particles?

Answer 1

Answer:

F= K q1q2/r^2

K is a constant uqual to= 9 x 10^9 N m^2 C^-2

F= 9 x 10^9 x 2 x 10^-3 x 8 x 10^-5/25

F= 1440/25= 58N
